The method of transmitting data around the ring is called token passing. A token is a special series of bits that contains control information. Possession of the token allows a network device to transmit data to the network. Each network has only one token.

Each computer passes along the data until the packet finds the computer that matches the address on the data. The receiving computer then returns a message to the sending computer indicating that the data has been received. After verification, the sending computer creates a new token and releases it to the network. The advantage of a ring topology is that it can handle high-traffic environments better than bus networks. In addition, the impact of noise is reduced in the ring topology. The disadvantage of a ring topology is that only one computer at a time can send data on a single token ring. Also, ring topologies are usually more expensive than bus technologies.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
